From de3d347f7b8a1a997fbc9267454ed6065068b969 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 8 Mar 2022 06:51:56 +0100 Subject: [PATCH] block: don't remove hctx debugfs dir from blk_mq_exit_queue The queue's top debugfs dir is removed from blk_release_queue(), so all hctx's debugfs dirs are removed from there. Given blk_mq_exit_queue() is only called from blk_cleanup_queue(), it isn't necessary to remove hctx debugfs from blk_mq_exit_queue(). So remove it from blk_mq_exit_queue().
